Four restaurant foods, taken apart on stage. Every number on this page came from the episode — press play and watch the plates build as Scott and Jenny talk through them.

Blood sugar sitting at 90, no insulin on board, flat arrow. Best-case conditions on purpose, so nothing muddies the picture. If your ratio is 1:6, your numbers are bigger — the shape is identical. 14:07

With meringue on top. Forty-nine of those carbs are in the pie before anybody touches the topping.

Jenny's problem with dessert16:27

It shows up at the end of a meal you've already bolused for.

  1. Look at the trend, not the number.Sitting pretty in range after a heavy meal tells you nothing about where it's going.
  2. Don't give the whole thing up front.Everything on the plate underneath it is slowing digestion down. Something like 25% now, the rest extended — two hours minimum.
  3. An extended bolus can be cancelled.That's the actual safety feature. Stop it if you're dropping, finish it if you're climbing.
Takeaway18:24

You can't count what you can't see.

A bowl of chili you can pick apart with your eyes. A pie is a mix — the sugar is already dissolved into it, and how much the baker pushed in is anybody's guess. Cheesecake does exactly the same thing to you.

The Cubana

Bread, pork, ham, Swiss, pickles — and butter, pressed right into it.

Everything has its impact. Take the protein out and you lose 1.28 units. Take the fat out and you lose about 2.2. Leave both in and the sandwich needs 3.49 units that have nothing to do with carbohydrate — and it wants them over eight hours.

What if you only eat half?24:16

Less fat and protein doesn't just mean less insulin. It means the tail is three hours shorter.

8–10g
One crab cake. How many carbs?
Four ounces, about the size of your palm. It's the crushed saltines holding it together, not the crab. Restaurants bring two — call the pair 15 grams and move on.
65g
One large russet potato, cut into fries.
One potato. Not a basket. Plus 8 protein and 14 fat once it's been in oil. A single potato is most of the carbs on this plate.
10g
Half a cup of coleslaw.
Cabbage is free. The dressing isn't — nearly all of it is the sugar in the dressing.

One cheese curd. How many carbs?
2–3g
Anything fried, thumb-sized, is about 3 grams of carb. Chicken fingers, mozzarella sticks, popcorn shrimp — judge it against your own thumb. Carbs only. It tells you nothing about the fat.

Count the carbs perfectly, dose them perfectly, and you have covered less than half of it. Then you spend the rest of the night wondering what went wrong.

And now, for no good reason

Eat all four.

Curds, crab cakes, Cubana, pie. In one sitting. As a life choice.

9.75 units short. Not because you counted wrong — because you counted the wrong things.

On the episode Scott added the meal up with the whipped-cream pie and without the ketchup — 235 carbs, 143 protein, 207 fat, 29.8 units. This page uses the meringue pie and the ketchup, the same versions as the plates above.

What that shortfall feels like36:48
One way it goes

You go low early

It's a lot of carbs, so you hit it hard up front. But all that fat is holding the food in your stomach and the insulin gets there first.

The other way

A sticky high, for hours

You dose, it doesn't move. You dose again. And again. Then the fat finally clears, all that stacked insulin arrives at once — and now you're low at two in the morning wondering what happened.

Same meal. Same person. The only difference is when the insulin showed up.

So what do you actually do37:30

Five moves for a meal like this

  1. Split it.Some now, the rest extended. Not all of it up front, ever, on a meal shaped like this.
  2. Stretch it long enough.Two hours minimum for dessert. This meal wants eight.
  3. Watch the trend, not the number.A flat 100 an hour in is not the same as a flat 100 that's about to climb.
  4. Use the cancel button.An extended bolus you can stop is a bolus you can afford to be generous with.
  5. Consider a temporary higher target.On a night like this, landing at 130 and staying there beats chasing 80 with a stack of insulin you'll regret at 2am.
